It is seal-welded to the body. ● Disc can partially rotate for tight shutoff. In the fully open position, it rests against a stop. ● CoCr alloy bearings for hinge pin. ● Easy in-line service. All parts are easily accessible for maintenance. Seating faces can be re-lapped. ● Forged bonnet. ● Size range(s) ● NPS 1/2 - 24 (DN 50 - 600) ● Pressure rating ● ASME Class 900 - 2500 ● Standard connections ● Socket weld, Butt weld CLASS 600~2500 PRESSURE SEALING SWING CHEEK VALVE Pressure sealing cover, swing type disc Threaded or welded seat ring ASTM A216 WCB,A217 Wc6,A351 Cf8,A351 CF8M, A351 Cf3,A351 CF3M,A351 CN7M Standards compliance Design and Manufacture: ANSIB16.34,API 6D,BS1868 Face to face(end to end): ANSIB16.10,API 6D Flanged connection: 2~~24~to ANSIB16.5 Butt welded end: ANSIB16.25 Test and inspection: API 598,API 6D A.
